我们考虑通过无序介质传输的非相互作用的量子粒子对，重点讨论它们的量子统计的作用。结果表明，由于介质散射通道中的玻色子聚束和费米子反聚束，传输过程中测量到的粒子数关联对粒子的量子性质非常敏感。文中还讨论了可分辨粒子的情况。
We consider pairs of non-interacting quantum particles transmitted through a disordered medium, with emphasis on the role of their quantum statistics. It is shown that particle-number correlations measured in transmission are strikingly sensitive to the quantum nature of the particles when they undergo Anderson localisation, due to bosonic bunching and fermionic anti-bunching in the scattering channels of the medium. The case of distinguishable particles is also discussed.
